void G_list_element | ( | const char * | element, |
const char * | desc, | ||
const char * | mapset, | ||
int(*)(const char *, const char *, char *) | lister | ||
) |
General purpose list function.
Will list files from all mapsets in the mapset list for a specified database element.
Note: output is to stdout piped thru the more utility
Given file name, and mapset, lister() should copy a string into 'buf' when called with name == "", should set buf to general title for mapset list.
element | database element (eg, "cell", "cellhd", etc.) |
desc | description for element (if NULL, element is used) |
mapset | mapset to be listed "" to list all mapsets in mapset search list "." will list current mapset |
lister | if given will call this routine to get a list title. NULL if no titles desired. |
